Abstract
Detection reagents, multi-analyte test elements, test systems, and multi-analyte measuring methods are provided. In particular, multi-analyte test elements have (1) a first working electrode and first counter electrode pair covered with a first analyte-specific reagent that includes an enzyme, a coenzyme and a first mediator and have (2) a second working electrode covered with a second analyte-specific reagent that includes an enzyme, a coenzyme and a second mediator, where the second mediator is different than the first mediator. The single counter electrode can be used as the counter electrode for both the first and second analyte measurements at their respective working electrodes. Moreover, the mediator concentrations, measurement ranges, and applied potential differences are not the same for each analyte-specific measurement.
